Calum Haggett claimed 3-38 to help Kent hold Glamorgan to 155-4 on a rain-hit opening day to their Division Two tussle at Canterbury.
Former Somerset seamer Haggett - who underwent heart surgery barely 18 months ago, enjoyed two useful stints from the Nackington Road End after Glamorgan had elected to bat in overcast conditions.
Charlie Shreck claimed the other wicket to fall in the 55 overs of play that were possible, though the former Nottinghamshire bowler was unfortunate not to have more success.
He saw chances go down at first and third slip during a naggingly accurate opening burst, leaving Haggett to enjoy two breakthroughs in the opening 10 overs.
The off-season signing had Will Bragg caught behind by Geraint Jones for five and then bowled Ben Wright when the opener foolishly shouldered arms that pegged back off stump.
Stewart Walters combined with Australian Marcus North to add an attractive 60 inside 20 overs for the third wicket before he perished for 38 to Shreck.
With the St Lawrence floodlights on, North moved smoothly through to 46 with three boundaries to his name until he was given out caught behind off Haggett, even if he appeared perplexed by the decision.
A pair of rain breaks and drizzle either side of tea served as a pre-cursor to the weather that followed and by 5pm umpires Steve Garratt and Neil Mallender had little option but to abandon play for the day.
Murray Goodwin was unbeaten on 35 for the visitors alongside Jim Allenby, who was 19 not out.
